Unexpected gallbladder cancer and laparoscopic surgery.

Case histories of three patients who underwent laparoscopic cholecystectomy for unexpected gallbladder cancer are reviewed. Port-site recurrence was observed in two of them. In one patient whose abdominal wall recurrent tumor was excised, a new recurrence developed, but after the reexcision she is symptom-free 10 months after the last procedure. The surgeon has to be aware of the fact that the survival rate can be doubled in stage pT2 if cholecystectomy is followed by extended radical operation. Only gallbladder cancer in stage pT1 does not need further procedure, except for excision of port sites. In case of uncertain diagnosis preoperative frozen section is recommended. Port-site recurrence does not mean an incurable stage of the disease or a sign of diffuse metastases. Even after reexcision of abdominal wall metastasis patients might be free from other detectable recurrences.
